STAPLE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 372,096, dated October 25, 1887. Application filed June 28, 1887. Serial No. 242,743. (No model.)

To all whom, it may concern.-

Be it known that 1, JOHN H. VINTON, of Boston, county of Suffolk, and State of Massachusetts. have invented an Improvement in Staple-Machines, of which the following description, in connection with the accompany- :ing drawings, is a specification, like letters on the drawings representing like parts.

This invention is an improvement upon the staple-machine shown and described in United States Letters Patent No. 345,464, granted to me July 13, 1886, and has for its object to pro vide the machine with an independent cuttingotf mechanism for the wire. The machine represented in said patent was designed to produce a staple having a crown and two legs, the ends of which were broadened and beveled, substantially as shown in United States patent granted to me August 11, 1885, No. 324,053.

The invention herein embodied consists in the combination, with a former over which the staple is bent, a vertically-reciprocating die for. bending the staple over the former, and hammers or hunters to strike and broaden the ends of the wire, of an independent cutting-off the clutch-pulley B, the eccentric B, its strap B*, the pitman B and plunger B, the die 0, carried by the plunger, the former a, with which the die co-operates to bend the wire in the production of the staple, the ratchet-wheel a and pawl a for feeding the wire forward intermittingly, the hammers or bunters m m and means for moving them to strike the ends of the staple after it has been bent over the former a, and the ejector for removing the finished staple from the former are all as in the patent referred to, and so do not need to b herein further described.

The cutting-oft mechanism consists of a bent rod, 50, one end of which enters a groove on one side ofth'e die 0, and the other end bears against the face of the eccentric B, which is provided with a cam or projection, 51.

A spring, 52, is employed to keep the rod against the eccentric B. As the shaft A revolves, the eccentric fixed to it moves the plunger B downward, causing the die a to descend upon the former a, the rod 50, bearing against the face of the eccentric B, also descending simultaneously with the die 0 until the projection 51 of the eccentric strikes the end of the rod 50 and moves it ahead of or V faster than the die 0, and the lower end of the rod 50 thus striking the wire s,.projecting from the blocks 2') and b and cutting off the wire just before the die 0 engages the wire to bend it over the former a. The block I) thus serves as the stationary member of a cutting-off mechanism and the rod 50 the movable member.

By employing an independent cutting-off mechanism it will not be necessary to make the die 0 of hardened steel, as heretofore, as the die itself forms no cooperative part of the cutting-off mechanism. While I have herein shown the rod 50 moved by the eccentric B, having a projection, 51, as the movable member of the cutting off mechanism, I desire it to be understood that I do not confine my invention to such construction, as it is obvious that many other forms of cutting-off mechanism may be employed, the essential feature of my present invention being to combine with the former, the 7 die, and hammers or bunters an independent cutting-off mechanism for the wire.

I claim 1. In a machine for making staples, the former over which the wire is bent, the die which co-operates with the former in the pro duction of the staple, and the hammers or bunters to strike, swage, and broaden the ends of the wire, combined with an independent cutting-off mechanism for the wire, substantially as described. 2. In a machine for'making staples, a former, a die, and means for moving the die, combined with a cutting-off mechanism consisting of a rod, 50, and means for moving it with the die for a greater part of its movement and for moving it ahead of the die to cut off the wirejnst I as the die engages the Wire, substantially as described.

3. In anmchine for making staples, a former and die, combined with a rod, 50, an eccentric, B, having the projection 51, for moving the said rod, and a spring, 52, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN H. VINTOX.
